Configuring the OS client for time synchronization
The OS clients only have simple network cards that neither send nor receive time message
frames. They query the time from the OS server in cycles and set their time accordingly. OS
clients query the time only from those OS servers from which they loaded data.
To configure OS clients for time synchronization, proceed as follows for each OS client:
1. Open the OS client in the PCS 7 project on the engineering station.
2. Select the "Time synchronization" editor from the tree view of WinCC Explorer.
3. Select Open from the shortcut menu.
The "Time Synchronization" dialog box opens.
4. Select the check box "Synchronization via terminal bus (slave)".
Thus all associated check boxes and text boxes can be selected.
5. Select the "Use time from a connected WinCC server" check box.
6. Click "OK".
Execute these steps for every OS client that will be synchronized.
